Antitheft door made from novel composite material

Abstract

The invention discloses an antitheft door made from a novel composite material and especially disposed an antitheft door material suitable for home life. In the technical scheme, the novel composite material is a carbon fiber reinforced ceramic-based composite material and a silicon carbide fiber reinforced ceramic-based composite material, wherein an inner surface is prepared from boron nitride. The novel composite material is mainly prepared through composition of the silicon carbide fiber and ceramic. The novel composite material not only can ensure a requirement of mechanical performances but also has an interface layer having an anti-oxidizing capability and a self-healing capability. The novel composite material not only has many excellent performances of a ceramic material, such as high strength, high modulus, excellent chemical corrosion resistance, excellent high temperature resistance and excellent oxidization resistance, but also has a metal-like breaking behavior, is insensitive to cracks and is free of destructive damage. The novel composite material is low in cost, is easy to obtain and is a preferably selection of composite materials.

Description

technical field [0001] The invention discloses a novel composite material anti-theft door, which is especially suitable for the anti-theft door material used in household life. Background technique [0002] At present, in the traditional anti-theft door, the anti-theft door material mainly made of iron material has low stability, is easy to corrode, and is easy to rust, which not only affects the appearance, but also shortens its service life, hindering its practical application. Therefore, we use a new type of anti-theft door composite material, which is mainly composed of silicon carbide fiber and ceramics to form a new type of composite material with high service temperature, high strength, high modulus, and good chemical corrosion resistance. , high temperature resistance and oxidation resistance, and the price is cheap and easy to obtain, so it has a good development prospect. Contents of the invention [0003] The object of the present invention is to provide a nove...
